Answer:
900 - 1= (31)(29)
Step-by-step explanation:
We need to factor 900 -1
We write each number in square form
900 can be written as 30^2
1 can be written as 1^2
[tex]900 - 1= 30^2 - 1^2[/tex]
Now we apply difference of square formula
a^2 - b^2 = (a+b)(a-b)
[tex]30^2 - 1^2=(30+1)(30-1)[/tex]
So 900 - 1= (31)(29)
